Nothing serious here today
Today is the operative word: we check Capitolguide every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
access
check_access
What access a visitor needs for a zone of the Capitol complex: (visitor_type × zone) → allowed?, credential, escort, lead time, required docs, security entrance, and the granting authority. INFORMS, never grants — final authority is the member office / Capitol Police / Secret Service. Rules are volatile and live-source-stamped.
accessible
accessible_route
Step-free / accessible directions between two points in the Capitol complex by mobility profile (wheelchair, limited_mobility, stroller, low_vision). Routes over elevators/ramps only, avoids stairs, and surfaces OCAS accommodation contacts. Use this instead of route_between when step-free matters.
capitolguide
capitolguide_prep
Pre-flight readiness check. Run before any other tool. Verifies secrets, KV, DB connectivity, and KB version + freshness. Returns a structured readiness report.
nearby
nearby
Nearest restroom, exit, and food for a specific point — a room code (floor-specific, e.g. the exact nearest bathroom to SH-217), a building name, or GPS coordinates {lat, lon}. Returns specific named venues ranked by distance.
overview
overview
Operational snapshot for the caller's tenant: KB version + freshness, queue depths (itineraries / draft meetings / active nudges), and the recent tool-invocation tail. Read-only.
plan
plan_day
Optimize a multi-meeting Hill day. Give a list of meetings (each a member name or room code, with an optional time like '10:30a'). Returns a sequenced itinerary: batched by chamber side to minimize cross-campus crossings, the route + minutes between each stop, the cross-campus window flagged, 'leave-by' times when meetings are timed, and warnings for connections too tight to make.
prohibited
prohibited_items
What you cannot bring into an area of the Capitol complex (security screening). zone: 'capitol_cvc' (the Capitol + Visitor Center — strictest, no food/water), 'gallery' (House/Senate galleries — no phones/cameras), or 'office_building' (the 6 office buildings — food & drink allowed). Always returns the universal weapon/hazard bans too. Volatile — live-source-stamped; confirm at visitthecapitol.gov before you travel.
room
find_room
Find a Capitol office by ROOM CODE (e.g. 'SH-217', '2310 Rayburn', '167 Russell', 'H-232'), by MEMBER NAME (e.g. 'Cornyn', 'Ted Cruz', 'Womack'), or by COMMITTEE ('Senate Judiciary', 'Ways and Means', 'House Armed Services'). A room code returns the decoded location plus who currently holds it; a name returns that member's current office; a committee returns its office / principal hearing room. Member & committee assignments are the 119th Congress (volatile, live-source-stamped).
route
route_between
Turn-by-turn directions between two points in the Capitol complex. Each point can be a room code, a building name, OR a Metro station / landmark (e.g. 'Capitol South Metro' → '2412 Rayburn', 'Union Station' → '517 Hart', or to the 'Supreme Court' / 'Library of Congress'). Returns an ordered step list with mode (walk/tunnel/subway), minutes, and a flag wherever you re-clear security. Set accessible=true for a step-free route (or use accessible_route).

Capitolguide — questions
Answers built from our own checks of this server.
What can Capitolguide do?
It exposes 9 tools, read directly from the server on our last check. Among them: accessible_route, capitolguide_prep, check_access, find_room, nearby, overview and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Capitolguide working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 160 ms. The bar chart above shows every period we have measured.
How do I connect Capitolguide?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Capitolguide need an API key?
No. Capitolguide completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Capitolguide?
It answers our handshake in 160 ms on average, which is faster than 80% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
